2014-06-09 (M) Upcycled 3D Printer

The
tensioning wheel was removed from the printer. A smaller rubber inline skate
wheel was selected to replace the large plastic wheel. The bearings and spacer
were removed from the plastic wheel. Speed rings, which are small washers
placed on the outside edges of the bearings, were added to reduce friction. A
longer bolt was purchased because it was fully threaded and long enough for
this application.

The
nuts were tightened around the wheel. After assembly and good testing the wheel
and bolt were placed into the printer. The bottom nut was adjusted for height
so the wheel pressed on the chain. Rubber bands were added to keep the wheel
tensed against the chain.

I started playing Pokémon GO when it came out. While playing I talked with a couple players, it's surprising social, and I heard about the bonuses from perfect throws. A throw is when you are facing a wild Pokémon and toss a Pokéball in an attempt to capture it. It's the same mechanics mobile app developers use to throw darts, bowling balls, baseballs, snowballs and other. It's an swipe from the bottom of the screen upward. If the user strays left or right the projectile will stray accordingly.

The key to a successful throw is to keep the finger from deviating from the path. I got to thinking about elaborate mechanisms with two or three servos holding a stylus, an Arduino to control them, a 3D printed frame and an elaborate rig to hold all this. Then I would need a battery because it would draw a lot of power. At that point I may as well use a huge battery and power the phone too.

After I got all that out of my system I had a Eureka moment where I threw out all the elabora…

A recording area was set up in my home office which meant clearing off a particularly filthy desk and setting up a camera. A tall tripod was set up and a tablet was attached so the script could be visible while recording. The script was written to have a pun in every sentence except for one.

The first attempt went poorly because only the Pi-ano audio was being recorded and there was no good pacing without reading out loud. Recording a voice-over to poorly paced video was a lost time-gamble. Well paced audio was recorded and played back while recording all new video so the pacing was perfect. This succeeded with the first take.

Setup for recording
Audio and video were combined and cropped to make a video that was less than 1:15. The whole evening was spent to make a one minute piano video but it hammers the point home.
